Angle encoder detection device

The invention, which belongs to the technical field of angle encoder quality detection, relates to an angle encoder detection device comprising a DC torque motor, a base, a first deep groove ball bearing, a motor shaft, an angle measurement shaft, and a second deep groove ball bearing. A first deep groove ball bearing and a second deep groove ball bearing on the front side and the rear side of the machine base are installed in the front shaft hole and the rear shaft hole respectively. A stator of the direct current torque motor is installed on one side of the machine base, a rotor of the direct current torque motor is connected to a motor shaft in a sleeved mode, and the motor shaft penetrates through the first deep groove ball bearing and is coaxially connected with an angle measuring shaft penetrating through the second deep groove ball bearing. On the other side of the machine base, the angle encoder is sleeved on the angle measuring shaft; the DC torque motor drives the rotor of the angle encoder to rotat
